Air Dried Oak Shadow Gap External Cladding

Our Air Dried Oak Shadow Gap External Cladding is shadow gap cladding in European oak, for external use.

About European oak

Air dried (seasoned) European oak, more stable and less prone to shrinkage than fresh sawn oak.

The boards are air dried outside for approximately 6 months, to between 16% and 25% moisture content.

Characterful boards that may show a small amount of sap on the underside, sound knots without limitation and occasional historic insect damage.

Supplied untreated.

Left alone it weathers to silver grey.

Profile and fitting

Shadow gap cladding gives a clean, linear look. Boards join with a 36 mm tongue/overlap on a 142 mm board, leaving a 106 mm visible face and a 10 mm recess between boards. Tongue stack 8 / 7 / 5 mm; opposite groove depth 10 mm.

They can be fitted horizontally or vertically; fit horizontal boards tongue uppermost so moisture runs off.

Grades and options

• First Grade: mostly clear of knots, with some knots up to 5 mm allowed and a small amount of sap on the underside only.
• Character Grade: sound knots without limitation, sap and occasional historic insect damage.
• End matching (tongue and groove on the board ends) lets you place joints where they fall rather than on a batten, which speeds up fitting and reduces wastage.

Good to know

• Use stainless steel fixings only. This is essential for oak: its tannin reacts with ordinary steel fixings and causes dark staining.
• Natural timber varies: expect some differences in colour and grain from board to board and from the photos.
• Boards left exposed to changing weather before fitting are likely to cup, warp and split. We suggest fitting between October and April where possible, within 7 to 14 days of delivery.
• Sizes are nominal and can vary slightly with moisture content.
• Not sure? Order up to two cladding samples first.
